Cloud Voice - Microsoft Teams
Teams Telephone Calls
Phone System is Microsoft's technology for enabling call control and Private Branch Exchange (PBX) capabilities in the Microsoft 365 cloud with Microsoft Teams. Phone System works with Teams clients and certified devices. Phone System allows you to replace your existing PBX system with a set of features directly delivered from Microsoft 365.
To connect Phone System to the PSTN, you can choose from the following options:
- Calling Plan. An all-in-the-cloud solution with Microsoft as your PSTN carrier.
- Operator Connect. If your existing carrier participates in the Microsoft Operator Connect program, they can manage PSTN calling and Session Border Controllers (SBCs).
- Direct Routing, which enables you to use your own PSTN carrier by connecting your Session Border Controller(s) (SBC) to Phone System.
- Others - Like 8x8 direct routing to Teams
